What is a key characteristic of a manic episode diagnosis?

To diagnose a manic episode, one of the essential criteria is the presence of at least three symptoms from the DIGFAST acronym: Distractibility, Insomnia, Grandiosity, Flight of ideas, Activities (increased), Speech (pressured), and Thoughtlessness (risky behavior). The requirement for these symptoms to be present for a duration of at least one week is crucial in establishing the diagnosis. This timeframe helps differentiate a manic episode from other mood states that may be shorter or less intense.

The other options do not accurately reflect the diagnostic criteria for a manic episode. For instance, hallucinations or psychotic symptoms are not mandatory for a manic episode; individuals can experience mania without such features. Additionally, mood changes are a fundamental aspect of mania, running contrary to the idea of it occurring without any mood changes.
